hi all- i'm having trouble with the following question but i have a feeling that its an easy question that i'm just looking into too much.
A moving shuffleboard puck has a glancing collision with a stationary puck of the same mass. The initial velocity for m1 = .95m/s. If friction is negligible, what are the speeds of the pucks after the collision?
I guess I tried thinking about the concept of the question and in my notes, we have where m1= m2 then the velocity of the moving particle will come to rest and the initially stationary particle will steal its velocity (v2=v). But the book is giving answers like .61m/s and .73 m/s. I tried finding the center of mass in which vcm = v1/2 = .95/2 = .475m/s but I dont know if that is needed or where i would even have to use that #.
I appreciate any help! Thanks! :)
